Revelation 9:1 - 3

[1] Then the fifth angel sounded: And I saw a star fallen from heaven to the earth. To him was given the key to the bottomless pit. [2] And he opened the bottomless pit, and smoke arose out of the pit like the smoke of a great furnace. So the sun and the air were darkened because of the smoke of the pit. [3] Then out of the smoke locusts came upon the earth. And to them was given power, as the scorpions of the earth have power. - Rev 9:1-3 NKJV

The armies of locusts in Revelation 9 are Islamic armies out of the Arabian Desert.  They overran the civilized world and spread Islam far and wide. 

This ungodly doctrine was developed in 620 A.D. and is a blend of Christian heresies, Jewish  rabbinical stories from the Talmud and Arabian superstitions. 

Islam – Apollyon, a destroyer, for that is his business, his design, and employment, to which he diligently attends, in which he is very successful, and takes a horrid hellish pleasure; it is about this destroying work that he sends out his emissaries and armies to destroy the souls of men.
